Notebook Series -- Notebooks by Experimenters Other Than Edison 
Phonograph Record Experiments -- W. W. Dinwiddie Disc Books 


These twelve notebooks relate to the work of William W. Dinwiddie and 
his assistants on the composition and manufacture of disc records during the 
years 1918-1920. The experiments are numbered from D1 through D821, 
although not all numbers have been used. Edison's involvement in the 
research is indicated primarily by the comments of other experimenters; there 
also infrequent notations and instructions in Edison's hand. Included are 
experiments aimed at producing the "perfect" record blank in terms of 
ingredients, varnishes, and the manufacturing process (mixing, pressing, 
baking, molding, and printing). Also included are occasional entries listing 
various chemicals and their characteristics or sources of supply, presumably 
to determine the best ones to use in the experiments. 


Experiments by Dinwiddie that are related to, but not directly connected 
with, the "D" experiments are described in N-19-08-20 {not selected]. The 
entries in N-19-04-23.1, N-20-03-01.1, and N-20-04-12 [not selected] are by 
Dinwiddie's assistants, Henry G. Atkinson, W. R. Simpson, Henry E. Thayer, 
and John Weichmann. The notes also indicate the involvement of Charles T. 
Dally, E. E. Dougherty, Charles G. Kircher, Ludwig F. (Louis) Ott, and others. 
Some of the experiments involve the use of mixes prepared in the C. T. Dally 
Disc Blanks Composition Books. Some of the "D" blanks described in 
Dinwiddie's books were used for further experiments documented in Dally's 
books. 


Four notebooks, representative of the work in the other books, have been 
selected for their numerous references to Edison's involvement in the 
experiments.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Phonograph Record Experiments -- W. W. Dinwiddie Disc Books 
Notebook, N-18-04-30 


This notebook was used by William W. Dinwiddie during April-July 1918 
for notes relating to the production of the blanks and submasters used in the 
manufacture of disc records. Edison's supervision of this work is indicated by 
Dinwiddie's references to his suggestions and by lists of chemicals referred to 
as "Mr. Edison's." The experiments are numbered from D1 through D100. The 
entries indicate differing methods of preparation involving variations in the 
baking schedules and the use of different ingredients, combinations of 
ingredients, and varnishes. Most entries contain comments about the results 
of the experiments, including whether the disk was cracked, rough, too stiff, or 
stuck to plates and molds during printing process. Also included are references 
to varnish experiments and to "drop tests" that were performed to determine 
the durability of the experimental blanks and submasters. There are occasional 
lists of chemicals ("materials obtained in N.Y."), along with notations regarding 
their characteristics and sources of supply. The notes indicate that Frank 
Clancy, Charles T. Dally, Charles G. Kircher, and Ludwig F. (Louis) Ott worked 
with Dinwiddie on these or related experiments. The front cover is labeled 
"Dinwiddie D-1 — 100" and "Disc Records." The pages are unnumbered. 
Approximately 110 pages have been used.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Phonograph Record Experiments -- W. W. Dinwiddie Disc Books 
Notebook, N-18-08-14 


This notebook was used by William W. Dinwiddie during August- 
December 1918 for notes on the production of disc record blanks. Edison's 
supervision of this work is indicated by Dinwiddie's references to his 
suggestions and his comments that Edison personally tested some of the 
materials. The experiments are numbered from D101 through D197. The 
entries indicate differing methods of preparation involving variations in the 
baking schedules and methods of applying the varnish and the use of 
different ingredients, combinations of ingredients, and varnishes. There are 
also illustrations of various ways to set up the presses and molds. Most 
entries contain comments about the results of the experiments, including 
whether the disc was too soft, sticky, or stiff and whether it had swell-ups, 
warps, or cracks. Also included is a description of an experiment "to 
determine what metals are most liable or less liable to stick to blanks when 
used as moulds." There are occasional lists of chemicals and other materials 
("materials obtained in N.Y."), along with notations regarding their 
characteristics, sources of supply, and prices. Inserted into the book is a 2- 
page memorandum from Dinwiddie regarding the procurement of stearic acid 
in New York City, along with Edison's response. The notes indicate that 
Charles T. Dally and Ludwig F. (Louis) Ott were working on related 
experiments. The front cover is labeled "Dinwiddie D-101 — 200/++/." The 
pages are unnumbered. Approximately 110 pages have been used.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Phonograph Record Experiments -- W. W. Dinwiddie Disc Books 
Notebook, N-18-12-07 


This notebook was used by William W. Dinwiddie during December 
4918-February 1919 for notes on the production of blanks and prints for disc 
records. There is one additional entry from March 1920. Edison's supervision 
of this work is indicated by occasional notations in his handwriting and by 
Dinwiddie's references to his suggestions and comments. The experiments are 
numbered from D201 through D347. The entries describe different methods of 
preparation and contain remarks about the results of the experiments, including 
how the prints made from each blank sounded. Several entries mention that 
a particular print sounded good or bad to Edison or that "Mr. E can not hear 
surface." Some entries note the expansion of blanks over a number of days. 
Also included are lists of chemicals and pigments, along with notations 
regarding their characteristics and sources of supply. The front cover is labeled 
"Dinwiddie Varnish D-201 -- Next book is 401--." The pages are unnumbered. 
Approximately 160 pages have been used.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Phonograph Record Experiments -- W. W. Dinwiddie Disc Books 
Notebook, N-19-01-10.1 


This notebook was used by William W. Dinwiddie and his assistant Henry 
E. Thayer during January-July 1919 for notes on the production of blanks for 
disc records. There is one additional entry from October 1919. Edison's 
supervision of the work is indicated by Dinwiddie's references to his 
suggestions and comments. The experiments are numbered from D401 
through D467. The entries describe the methods used in the manufacture and 
preparation of the blanks, particularly the baking process, and contain remarks 
about the results of the experiments. Several indicate that a particular print 
sounded good or bad to Edison or that"Mr. E can't hear surface." Also included 
are lists of clays, along with remarks about their characteristics, sources of 
supply, and prices. The notes indicate that W. R. Simpson assisted Dinwiddie 
in some of the work and that Charles T. Dally used some of the same materials 
as Dinwiddie in his experiments. Pasted into the book is a one-page note by 
Edison pertaining to a patent on a shellac substitute that he wanted Dinwiddie 
to try. The front cover is labeled "Dinwiddie D-401 -" and "Disc." The pages are 
unnumbered. Approximately 100 pages have been used.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Phonograph Record Experiments -- Disc Plating Books 


These sixteen notebooks, which cover the years 1912-1916 and 1920, 
relate to the plating processes used in producing disc records. Most of the 
entries are by William W. Dinwiddie. Other employees who are identified as 
working on similar experiments include Charles Beaumont, A. Boetsch, Leroy 
E. Briggs, Peter C. Christensen, Peter Dempsey, William A. Hayes, John 
McMullen, F. Meschmeyer, Joseph Miller, Frederick P. Ott, Elroy Pearsall, 
and Albert F. Wurth. 


The experiments in these books were aimed at improving the plating 
practices involved in making masters and submasters for disc records and at 
resolving specific problems in current practices. Edison's in this work is shown 
by references to plating experiments performed by him, as well as by 
references in several books, particularly N-13-04-04.2, to statements made 
by "Mr. E." The gap in plating work from 4916 to 1920 in this subgroup, as 
well as in the Notebooks by Edison series, is most likely due to Edison's 
decision to concentrate his efforts and his staff on work for the Naval 
Consulting Board and inventions for the U.S. Navy. 


Although the notebooks in this subgroup are loosely related to each 
other, they deal with a variety of experiments. For example, there is a set of 
three books consisting of daily records of masters, their plating, and the 
results of the plating. Included are entries with some or all of the following 
information about the experiment: an identifying number for the record, the 
title of the recording, the recording artist, the type and condition of the record, 
room and bath temperatures, times and amps for the bath, and a report on 
results. Some books contain lists of various experimental plating solutions 
and their ingredients. Other books include plating "schedules" and formulas 
for various solutions used in the plating process. There are also books 
describing experiments with various ingredients, such as graphite, and 
different parts, such as anodes, that were used in the plating process. 


Two notebooks have been selected because they include secret 
formulas and processes used in the plating of Edison disc records and 
because of their strong indication of Edison's involvement.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Phonograph Record Experiments -- Disc Plating Books 
Notebook, N-13-09-27 


This notebook was used by William W. Dinwiddie during September 
4913-August 1914. One additional notation was probably made in February 
1915. The book begins with the inscription, "Let no one see this book without 
very definite orders from Mr. Edison." The entries consist primarily of a series 
of formulas, along with instructions describing current practices for plating the 
masters and submasters used in making Edison disc records. These were 
probably the culmination of numerous plating experiments documented in 
earlier books in this subgroup. Additional experimentation produced 
modifications in formulas and practices. For example, the use of submasters 
was discontinued shortly after 1913. Some of the formulas have been crossed 
out and changed, with an indication of the date on which the practice changed. 


Among the practices described in this notebook is the method of 
preparing "dopes" (caminol and copper ink) for use in plating the wax masters, 
along with an indication of the object of using each dope. Also included is a 
description of the method of purifying the graphite used to make a conducting 
surface on the wax. In addition, there is a description of the formula and 
method of molding the wax masters, as well as an analysis of the defects in 
disc molds. There are indications that H. Grimes worked with Dinwiddie on 
some of these experiments. Several notes and letters to and from Dinwiddie 
dating from 1917-1920 are inserted into the book. The front cover is labeled 
"Copper Plating Phonograph Records.” The book contains 28 numbered 
pages; some pages are blank.

Re = Raw Material for Disc Masters:= 


Stearic Acid:= i 
Copy of letter to Purchasing Depte June 20-I916 attached shows what 
we have dons. j 
The practical test referred to was to make a small sample of Wax as follows:~ } 
4.64 grammes Caustic Soda ; 
1.80 " Aluminum 
I0I.60 us Sal Soda 
II5d. CC water 


Boil until all aluminum is dissolved and dilute to 300 CC. 
Zhis is enough for 9 test batches of wax as follows:— 
- 5025 ge Stearic acid from each sample. 
33 1/3 cco of above solution. 

put solution into the melted stearic acid slowly temp. 330 F. raise temp 
to 420 F.until foaming stops ; add 3.788 grammes of FFF valve oils raise : 
temperature to 450 F for two or three minutes stirring thoroughly with | 
thermometer. Mould into a 2s" diameter disc. 

In testing a new sample a check test should be made using some—stearic-- nae 
acid which we are using now, or know about, so that we may not bé thrown off 
by some variation in the other ingredients. SE ere ee | 

The discs are then cut flat on one edge and mrt of om face 2) ae 
to expose a cut surface. They are then placed in plating © lution half ‘ 
emersed for 24 hours to see if the wax is attached vy the solutions Thave, 
usually drilled a hole in center of each and strung then on a wire to prevent ~ 
their falling over in the solution. ; 

Oleic Acid causes the wax to be attacked by air; Mr. Aylesworth considered 
3% the danger line. - 

We have never had anything like 3% Oleic in the tripple pressed stearic 
acid, and have never had any trouble from ite 

FRF Valve O11 made by Standard O11 Company ; this is tested by casting 
small discs same as we test the stearic acid, but we start with hard wax and 
take 50 @ of hard wax (wax made without o11, but complete otherwise) and add 
3} grammes of each sample of 011. Te best is the one least attacked by the i 
solution - but it has to stand a more important test ani furnish a proper ‘ 
softener to give the wax the right cutting qualities. This can only be | 
determined by making up Disc Masters and recording on them. A considerable 
difference might not be apparent until a change of season from Suamer to ! 
Winter might make it impossible to use the wax. : 7 

The Caustic Soda is the same as used by the Edison Primary Battery. ~~ | 

The Sal Soda met be recrystalized. 

This is not a matter of purity, but the anhydrous will not combine with : 
the aluminome 

Iz the weight is not all crystals, the proportions are not correct. 

The aluminum we have been using is rolled sheet metal which we have not 

tested in any way but buy it ors commercially pure aluninum, 

Ig there is anything not quite clear in the preceeding, or if I can 

be Of any further service in regard to this matter, please call on me.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Phonograph Record Experiments -- Disc Plating Books 
Notebook, N-14-05-28 


This notebook was used by William W. Dinwiddie in May and June 1914. 
At the beginning of the book are formulas for a silver solution, a reducing 
solution, and a washing solution; these formulas also appear in other books in 
this subgroup. Most of the entries describe experiments with "commercial" 
records or submasters washed with gold dust. The results and appearance are 
noted. There are occasional references to experiments by Moore, probably 
Sherwood T. (Sam) Moore. Also included is a list by Edison of suggested 
chemicals, with a notation that he will make additional suggestions if these do 
not work. The front cover is labeled "Silver Plating W. W. Dinwiddie May 
4914." The book contains 28 numbered pages; some pages are blank.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Phonograph Record Experiments -- Record Varnish Books 


These five notebooks were used primarily in 1913 and 1914 by William 
W. Dinwiddie and Sherwood T. (Sam) Moore for notes on the varnish used for 
Edison disc records. One book has a few entries from 1916. Other 
experimenters who are identified as doing related work include Charles T. 
Dally, H. Grimes, and Archie D. Hoffman. Included are tests of various 
experimental varnishes and different methods of varnishing, along with tests 
of how certain conditions affected the varnished record. Also included are 
experiments aimed at resolving specific problems, such as preventing wave 
formation on the records during varnishing. Some of the work in these books 
is related to experiments by Edison, Dinwiddie, Hoffman, and Moore in a four- 
book set beginning with N-14-04-30 (see Notebooks by Edison). 


Two books have been selected for indications of Edison's involvement.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Phonograph Record Experiments -- Record Varnish Books 
Notebook, N-14-02-23.2 


This notebook was used during February-June 1914 by Sherwood T. 
(Sam) Moore and probably J. W. Poole for notes on experiments with 
varnishes, presses, and manufacturing processes for disc records. Also 
included are entries relating to experiments with powder blanks and with 
loading the blanks into the machines. Defects in the varnished disc records or 
prints are indicated. Charles T. Dally and Archie D. Hoffman are mentioned as 
doing related work, and some of the entries may be by Dally. There are also 
instructions from Edison to Moore pertaining to proposed experiments with disc 
record blanks. Some of the entries include a notation that the experiment was 
done for Edison. Pasted into the book is communication from Edison's 
personal assistant William H. Meadowcroft containing a description of Moore's 
work. Among the loose items inserted into the book is a one-page note in

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Phonograph Record Experiments -- Record Varnish Books 
Notebook, N-14-05-14 


This notebook was used during May 1914 by an assistant in the chemical 
laboratory named Davis (possibly W. B. Davis, author of N-20-07-27 
[unselected]). The entries relate to experiments to prevent wave formation on 
records while varnishing. Most of this work involved the use of various resinous 
compounds, particularly phenolic resin. Some entries refer to a "Mr. T. A. E. 
idea," while others indicate that something was given to Edison for further 
experimentation. The flyleaf is inscribed "Note book of Mr. Davis." The front 
cover is marked "Davis." The book contains 5 numbered pages followed by 
approximately 25 unnumbered pages.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Phonograph Record Experiments -- Cylinder Books 


These three notebooks were used by John P. Constable, Sherwood T. 
(Sam) Moore, and James Toy in 1914 and 1918-1921 for notes on experiments 
to improve Edison's cylinder records. These books indicate that the inventor 
was still interested in the cylinder format as late as 1920. One book contains 
notes and drawings relating to various possible improvements in the Model X 
Amberola. Another contains entries pertaining to the press used to make Blue 
Amberol cylinders and the printing schedule for these records. Also included 
are notes on experiments dealing with the composition of cylinder records. 


One book has been partially selected for indications of Edison's 
involvement.

Notebook, N-20-10-25 


This notebook was used in 1920-1921 by James Toy for notes on 
experiments to improve the quality of Blue Amberol cylinder records. These 
experiments, which were carried out under Edison's directions, illustrate the 
inventor's commitment to the cylinder format as late as 1920-1921. The 
experiments involved a variety of materials, including rubber cement, linseed 
oil, and collodion. A note by Toy bearing a response from Edison, as well as 
some brief instructions by Edison, have been taped into the book. The front 
cover is labeled "706-x-1." The book contains 139 numbered pages followed 
by approximately 50 unnumbered pages. 


Only the two pages with Edison notations have been selected.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Phonograph Record Experiments -- F. Detlef Disc Books 


These three books were used in 1920 and 1921 by Frank Detlef, Jr., for 
notes on experiments on the plating solution used in producing disc records 
and in the master plating process. There are also references to work done by 
Ludwig F. (Louis) Ott and Howard F. Redford. Some of the entries consist of 
a day-to-day record of analysis of the plating solutions and electrolyte control 
for the Disc Record Plating Department. Also included are experiments 
regarding attempts to improve the plating process by increasing the speed, 
substituting different types of plating, and casting a wax or plaster backing 
(instead of copper) for the thin nickel face plated from the master. The books 
contain some work on experimental disc composition by Detlef. Notations in 
two books indicate that Detlef was reporting directly to Edison. 


Portions of the first book have been selected as a representative 
sample.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Phonograph Record Experiments -- F. Detlef Disc Books 
Notebook, N-20-01-05 


This notebook was used by F. Detlef, Jr., during January-September 
1920 as a daily record of analysis of electrolytes used in disc record plating. 
Detlef took samples and calculated specific gravity, acidity, and the amount of 
nickel, copper, iron, and aluminum. inserted into the book are two notes by 
Edison regarding items to which he wanted Detlef to pay attention. Detlef refers 
to Edison's oversight at several points with phrases such as "Mr. Edison says" 
or"keep Mr. Edison informed." There are also references to work by Ludwig F. 
(Louis) Ott, as well as some loose notes [not selected] in Ott's hand. The flyleaf 
is marked "F. Detlef Book #2 - on Electrolyte Control for the Disc Record 
plating dept." The pages are unnumbered. Approximately 125 pages have 
been used. 


The entries from January have been selected as a representative 
sample. Several loose notes by Edison have also been selected.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Phonograph Record Experiments 
Miscellaneous Disc Composition Books 


This set of eight loosely related notebooks, which covers the years 1911- 
4921, contains a variety of experiments relating to the composition of Edison 
discrecords. The experimenters include Charles Dally, Archie D. Hoffman, and 
W. Jones. The notes indicate that Edward L. Aiken and A. Petit (Ademor N. 
or Albert O.) worked on related projects. Included are experiments with shellac 
and various varnishes aimed at improving the discs, with reports on the results 
and condition of the records printed. Some entries involve the use of alternative 
materials for the disc blank, such as plaster of paris and paper. Also included 
are notes on disc manufacture and "transfers," which provide information on 
the preparation of the blank and details of transfer schedules. Several 
experiments conducted during World War | pertain to attempts to adjust for 
shortages of certain ingredients, such as celluloid and lampblack. There are 
also experiments involving the reuse of discarded discs. The work in N-16-04- 
26 is related to the experiments in Notebooks by Edison and Other 
Experimenters—Disc Record Books, Nos. 1-26, while N-20-11-12 is related to 
the C. T. Dally Disc Blanks Composition Books, Nos. 1-14. 


One book containing experiments performed on direct orders from 
Edison has been selected in its entirety. Another book has been partially 
selected for indications of Edison's involvement.

Notebook, N-11-04-17.2 


This notebook was used by W. Jones in 19114 for notes on experiments 
involving the shellac used to coat the Edison disc records that would be put on 
the market in 1912. The object of the experiments was to reduce blisters, 
smears, and other imperfections. The notes indicate that A. Petit (either 
Ademor N. or Albert O.) collaborated with Jones on the new disc records. One 
note by. Edison has been inserted into the book. The front cover is labeled 
"Shellac # 2064" and "W. Jones, Chemical Laboratory." The pages are 
unnumbered. Approximately 50 pages have been used.

Miscellaneous Disc Composition Books 
Notebook, N-16-04-26 


This notebook was used by Archie D. Hoffman during April 1916 for 
experiments on disk "transfers" performed on orders from Edison. The 
experiments have "E" numbers that correspond to the experiment numbers in 
N-16-03-07 and N-16-04-27, Notebooks by Edison and Other 
Experimenters—Disc Record Books, Nos. 1-26. The notes provide information 
on the preparation of the blank, such as varnish details, along with details of 
transfer schedules, such as temperatures, times, and pressures. The pages 
are unnumbered. Approximately 30 pages have been used.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Phonograph Record Experiments -- W. W. Dinwiddie Disc Mold Books 
[Not Selected] 


These three books were used by William W. Dinwiddie in 1915, 1918, 
and 1920 for notes on miscellaneous experiments, some loosely related to the 
"D" experiments in the Dinwiddie Disc Books, to improve the molding of blank 
disc records. Included are experiments with varied ingredients for the wax and 
various tests on those waxes. The results often note how the wax melted and 
how well it loosened from the disc blank mold without melting. Other entries 
pertain to experiments with the powder in disc composition and its effects on 
the molds, as well as with various methods of loading the molds. Also included 
are notes on experiments to reduce wear on the molds and to protect them 
from excessive pressure from the hard blanks in the mold presses. The 
problem was eventually resolved by pre-softening the blanks within the presses 
with steam heat before physical pressure was applied.

Phonograph Record Experiments -- Record Inspection Books 
[Not Selected] 


These seven books were used during August-December 1917 by Archie 
D. Hoffman and an unidentified assistant for statistical records of numbered "E" 
experiments. Each experiment usually involved a set of printings of a disc. For 
each printing, there is information about the number of records inspected, the 
number and percentage of "O.K." records, and the problems with each 
discarded disc. The reasons given for discard include pull-outs, crushed edges, 
cracks, and rough spots. Some of the results in these books were transferred 
to books in Notebooks by Edison and Other Experimenters—Disc Record 
Books, Nos. 1-26.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Phonograph Record Experiments -- Blank Transfer Inspection Books 
[Not Selected] 


These three books were used in 1915 by three unidentified employees 
for notes regarding the inspection of experimental powder blank transfers. They 
are probably part of a larger series, the remainder of which is no longer extant. 
The entries indicate the varnish lot, blank number, oven number, and the 
reasons for discarding, such as cracks, thin margins, pull-outs, "birds," pin 
holes, cracked varnish, and mechanical defects. Some of the notes refer to 
"special" or "commercial," rather than experimental, blanks. The initials next to 
the dates on some of the entries may be those of the experimenters.

Phonograph Record Experiments 
Miscellaneous Experiment Books [Not Selected] 


These eight notebooks, which cover the period 1911-1920, encompass 
a variety of experiments by Zachariah P. Halpin, Albert F. Wurth, and other 
employees. Included are reports on disc original masters and master molds not 
completed, data on the printing and transferring of experimental records, and 
information regarding the quality of printed records. One book describes the 
physical equipment, mold holders, rotators, and tables used for electroplating. 
Also included are experiments on improving the wax used in disc records, on 
the heat in the record manufacturing process, on the springs in recorders and 
phonographs, and on reproducers. One book contains information about repair 
of phonograph parts, machine tools needed for phonographs, and the care of 
phonographs and cabinets. Another has entries on cabinet design, along with 
tests of mechanical parts, such as turntable springs and governors.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Group 2: Kinetophone and Kinetoscope Experiments (1911-1914) 


These nineteen notebooks cover the period 41911-1914. They were used 
by Leroy E. Briggs, William W. Dinwiddie, Harry W. Doyle, Zachariah P. Halpin, 
Absalom M. Kennedy, James W. Ramsay, and other Edison employees for 
experiments relating to the development of motion pictures. Included are tests 
of Edison's home projecting kinetophone, as well as a "professional" variation 
of the machine. There are also notes pertaining to the kinetophone (motion 
pictures with sound), including tests to determine the optimal positions of the 
kinetoscope and phonograph for synchronization and experiments with the disc 
diaphragm. Other entries describe the development of complete kinetophone 
and home kinetoscope outfits and demonstrations of the kinetoscope. 


in addition, there are experiments to ascertain the best carbon element 
for the "motion picture machine" and data regarding the use of an incandescent 
rather than arc lamp. Other entries describe the development of a new lamp 
house, commutators, lens systems, screens, an automatic film developing 
machine, and a film drying machine. There are notes on various setups for the 
developing machine and variations in airflow, blowers, and vents to test the 
heat regulation. In addition, there are tests of noninflammable film, a paper 
fastening machine, new film cement, amplifiers, synchronizers, and cameras. 
Other experimenters who are identified as working on related projects include 
Adolph F. Gall, Daniel Higham, Charles W. Luhr, Charles W. Norton, Elroy 
Pearsall, and George J. Werner. Seven books with indications of oversight or 
involvement by Edison have been selected. 


The notebooks are arranged in three subgroups: (1) L. E. Briggs Books 
(6 notebooks); (2) A. M. Kennedy Books (6 notebooks); (3) Miscellaneous 
Books (7 notebooks) [not selected].

Kinetophone and Kinetoscope Experiments -- L. E. Briggs Books 
Notebook, N-13-03-18.2 


This notebook was used by Leroy E. Briggs during March-May 1913 
mainly for experiments relating to the development of Edison's home projecting 
kinetoscope. The initial entry describes formulas for a silvering solution for 
plating glass. The remainder of the book is primarily a daily log of Briggs’ work 
on the kinetoscope; the log is continued in N-13-05-22 [not selected]. Included 
are experiments aimed at adapting the incandescent amp for use in the home 
kinetoscope. Other notes describe the work of Briggs and a machinist named 
Dennis on the development of an adjustable contact apparatus for the 
kinetoscope. There are also descriptions of new lamp holders and 
commutators. Some of the entries in the middle of the book contain data on 
endurance tests for General Electric bulbs that might be used in the 
kinetoscope. Other experiments involve the use a corrugated aluminum 
screen, reflectors, and various lens systems. in addition, there are experiments 
to make the telephone receiver in the kinetophone less bulky and better able 
to fit into a limited space. A series of entries toward the end of the book 
describes tests of a frictional microphone for train dispatching. Miller Reese 
Hutchison directed some of this work, and Briggs produced weekly reports for 
him. The results of some of the experiments were shown directly to Edison, 
who commented on them and sometimes gave additional instructions. The 
notes indicate that Briggs consulted or received instructions and assistance 
from Ernest J. Berggren, Adolph F. Gall, Zachariah P. Halpin, L. E. Hammond, 
Absalom M. Kennedy, William H. Meadowcroft, Henry J. S. Rudolf, and Carl 
H. Wilson. The cover is labeled "Experiments with Lights, and Lenses in Home 
Kinetoscopes. Also Aluminum Screens. L.E. Briggs | March 18 to May 21, 
1913." The book contains 13 numbered pages followed by approximately 95 
unnumbered pages.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Kinetophone and Kinetoscope Experiments -- L. E. Briggs Books 
Notebook, N-13-09-17 


This notebook was used by Leroy E. Briggs during September 1913- 
January 1914 for experimental notes on an automatic film developing machine. 
The book consists primarily of a daily account of Briggs's activities, including 
experiments with new or improved parts made for the machine. There are 
occasional references to work on the home projecting kinetoscope and to the 
“other book" (N-13-05-22 [not selected]). The notes indicate that Briggs's work 
on the developing machine was overseen by Edison and Miller Reese 
Hutchison. There are occasional notations regarding Edison's opinions or 
suggestions. The notes also indicate that William W. Dinwiddie, Absalom M. 
Kennedy, Charles W. Luhr and James W. Ramsay were involved in similar 
work. The front cover is labeled "Automatic Machine for Developing, Fixing 
and Drying Motion Picture Film. L.E. Briggs SO. 3300." The pages are 
irregularly numbered. Approximately 75 pages have been used.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Kinetophone and Kinetoscope Experiments -- A. M. Kennedy Books 


These six books were used by Absalom M. Kennedy during 191 3-1914 
primarily for experiments on the kinetophone. There are entries pertaining to 
the making of kinetophone recording outfits, adjustments based on 
recommendations or testing, and experiments with various motors and other 
parts. There are also recording tests to determine the optimal stage positions 
for actors and props as well as other filming conditions. Some of Kennedy's 
notes describe meetings of the "kinetophone experimenters" and the tasks 
assigned to them. A few relate to the recording experiments in Notebooks by 
Edison and Other Experimenters—Recorder and Recording Experiments— 
A. M. Kennedy Books. Several entries contain notations that Kennedy was 
reporting to Miller Reese Hutchison. In some cases, he received instructions 
directly from Edison on projects to be undertaken, along with comments and 
suggestions. The notes indicate that Adolph F. Gall, L. E. Hammond, Daniel 
Higham, Charles W. Luhr, and George J. Werner were doing similar 
kinetophone-related projects. A few experiments by Kennedy on kinetophones 
and motion picture film, as well as references to kinetophone demonstrations, 
can be found Notebooks by Edison and Other Experimenters—Recorder and 
Recording Experiments. 


The five books with indications of oversight by Edison have been 


selected.

Kinetophone and Kinetoscope Experiments -- A. M. Kennedy Books 
Notebook, N-13-04-20 


This notebook was used by Absalom M. Kennedy in April 1913 as a 
record of experimental work on the kinetophone. Included is a description of 
the making of three complete kinetophone recording outfits—one for Europe, 
another for the laboratory, anda third for reserve. The entries provide extensive 
details about each outfit, including camera, synchronizer, storage batteries, 
recording machine, amplifying machine, shaving machine, and blanks. They 
also describe adjustments made on the basis of recommendations or testing. 
Some final entries contain data regarding tests of business phonographs and 
motors. Also included are entries pertaining to meetings of the "kinetophone 
experimenters” and the tasks assigned to them. The notes indicate that Adolph 
F. Gall and George J. Werner were also doing kinetophone-related work and 
were consulted by Kennedy. There are tabs cut into the pages labeled 
"Camera," "Recorder," "Amplifier," "Shaver," and "Miscellaneous." The front 
cover and spine are each labeled "Kinetophone Studio Ouifits." The pages 
are unnumbered. Approximately 50 pages have been used.

Notebook Series -- Notebooks by Experimenters Other Than Edison 
Kinetophone and Kinetoscope Experiments -- A. M. Kennedy Books 
Notebook, N-14-01-01.3 


This notebook was used by Absalom M. Kennedy during January- 
February 1914 as a record of experimental work on the kinetophone. There are 
a few additional entries from December 1914 and January 1915. Included are 
experiments on frictional reproduction, motor regulation, and synchronous 
motors. The entries describe comparison tests between various brands of 
equipment, as well as inspections of records and reels for foreign orders. Also 
included are tests on kinetoscope shutters and film cement. At the end of the 
book is a list of ideas for improving the kinetoscope. The notes indicate that 
Kennedy received instructions directly from Edison on the work to be 
performed, along with comments and suggestions. There are also indications 
that John W. Farrell, Adolph F. Gall, Daniel Higham, and Charles W. Luhr were 
involved in similar work. The front cover is labeled "Jobs Undertaken. Jan. 1, 
1914. & Kinetoscopes Ideas." The book contains 200 numbered pages and an 
index; many pages are blank.
